The BT50 is a uniquely designed brake tester for the testing of brakes on trackless mining machines (TMM) as per either SANS 1589:2012 and/or ISO 3450:2011

The BT50 is designed as a stand-alone unit that is permanently installed at a mine at or close to the workshop where the machines are serviced. The brake tester can test all the brake systems i.e. service, neutral and park/emergency brakes with a full traceable report which is time and date stamp with a picture of every test. The brakes/systems are also tested with a 10% overload to enable trending of the brake degradation. The ideal is that the brakes are tested after every service thereby excluding gray areas around testing after intervention.
